5 In its simplest form, the LED class just allows control of LEDs from
7 LED is defined in max_brightness file. The brightness file will set the brightness
8 of the LED (taking a value 0-max_brightness). Most LEDs don't have hardware

18 Complex triggers whilst available to all LEDs have LED specific
19 parameters and work on a per LED basis. The timer trigger is an example.
20 The timer trigger will periodically change the LED brightness between
23 You can change the brightness value of a LED independently of the timer
